Aluminum sulfate is a widely used industrial reagents, often confused with alum. Under natural conditions, little to no aluminum sulfate salt form. It will form a hydrate, including 16 water aluminum sulfate is the most common.

Chemical Properties
Easily soluble in water, aluminum sulfate in pure sulfuric acid insoluble (only co-exist), in sulfuric acid and sulfuric acid together dissolved in water solubility of aluminum sulfate in sulfuric acid is aluminum sulfate in water solubility.
Precipitation at room temperature with 18 molecules of crystal water, aluminum sulfate to 18, more than 18 industrial production of aluminum sulfate. 51.3% with anhydrous aluminum sulfate, 100 degrees and will not even dissolve (dissolved in its own crystal water).
Easily weathered the loss of crystal water, more stable, heat will be water loss, high temperature will decompose to alumina and sulfur oxides
